T0 all wh0m zt may c0ncern:

Be it known thatwe, WILLIAM II. AMES anal MONROE GRIER,bOIJI1 of the city of St. Louis, in the State of Missouri, have invented a 0ertain new and useful Improvementin Fans, of whioh the following is a full, clear, and exaot description, referenee being had to the aocompanying drawings,forming part of this speoification.

Our invention relates to an improvecl device for operauing a fan or a number of fans; and our invention consists in features of novelty hereinafter fully clescribecl, ancl pointecl out in the olaims.

Figuro I is a side elevation illustrative of our invention. Fig. II is a horizontal section taken on line II II, Fig. I. Fig. III is an en largecl detail vertical section of the shaft-inolosing tuloes ab the point where they -aro joined. Fig. IV is an enlargecl vertioal section taken on line IV IV, Fig. II. Fig. V is a similar view taken on lineV V, Fig. II. Fig. VI is an enlarged encl elevation of tl1e base of the device, showing the treadle by whioh the spring is wound up.

Referring to the drawings, 1 reprosents a table in oonneotion With whioh the fan 1nay be used or alongsicle of wl1ich tl1e fan may be plaeecl.

2 represents a base or housing inolosing a spiral spring 3, as shown in Fig. II. The spring surrounds a rod 4, supported in the ends 5 of tl1e base 2. Tl1e outer end of the spring is seourecl 130 the mernber 6 of a olutch, -which is mountecl loosely on the rod 4 and Which engages the other member 7 of the clutoh, whioh is securecl to therod. The unember 6 of the olutch has a notohecl flange 8, (see Fig. V,) with whioh engages a (log or pawl 9, secure l to the base, and whioh prevents the baokwarcl or retrograde movement of ehe member 6 of the olutch. The inner end Cf the spring is macle fast or seoured, as shown in Fig. II, to a l1ub 10 of a sleeve 11, through which the rod 4 passes.

The sleeve 11 is journalecl in a partition 12 of the base 2, as shown in Fig. II. 011 this sleeve and permanently secured to it is a 00gwheel 13, whioh meshes into a pinion 14. The cog-wheell3 is loosely mounteclon therod 4 ancl turns freely thereon. The pinion 14 is mounted loosely on a pin or shaft 15, journaled in the sides of tl1o baso or housing. Seourecl to the pinion 11 is a .eog-wheel 16, whioh is also loosely mounted on its shaft or pin 15, and whioh engages apinion 17 ,seoured to 01 formed integral With a cog-wheel 13, the pinion 17 and wh eel 18 bein g loosely mounted on the rod 4. 'll1e oog-wheel 18 engages a pinion 19, formed integral with or securecl to a bevel-wheel 20, fuhe pinion 19 ancl bevel-wheel 20 being loosely mounted on the pin or shaft 15. The bevolwl1eel 20 is arrangecl in a vertioal position and engages a oorresponding wheel 21, arrangecl in a horizontal position ancl secured to the lower end 01: a shaft 22, which passes up through the top of the base or housing within a sleeve or tube 23. The gearing wo have just clescribecl is besb shown in Figs. II and IV. Tl1e tube or sleeve 23 extends upwardly to a suitable point, as shown in Fig. I, where it has a joint 24, as shown in Figs. I and III, ancl from whero a goose-neck sleeve 25 oxtends. The sl1aft 22 extends upwarclly from the joint 24, where it is providecl with a 001- lar or hulo 26, to tl1e upper encl of whioh is securecl a flexible shaft 27, forxnecl in tl1e usual way of ooiled wire. The conneotion between the hub 26 ancl the upper end 0f the shaft 22 is preferably macle by forming a non-oircular sooket in the formor,into which the non-oircular encl of 911612113901 fits. The flexible sheift 27 passes through the tuloe 25 and protrudes therefrom, as shown at 28, Fig. I, and to its outer encl is seourecl one or more fans 29, whieh are revolved or turnecl by the shaft.

* At the joint 21 wo preferably plaoe a setsorew 30, the inner encl of whioh bears against the oollar or hub 26 to form a friotion-brake by whioh tl1e speecl of tl1e fans 1nay be regulatecl.

The inner encl of the shaft 4 extends boyoncl tl1e base or housing, as shown in Figs. I ancl II, anti upon il: is seoured atreaclle 31, which may be raised by a spring 32.

The operation is as follows: By applying the foot 110 t-l1e treadle 31 am]. moving it up and clown power is stored in the spring 3, the member 6 of the elutoh slipping around on the member 7. \Vhen sufficient power has been stored in the spring, the foot is removed. 'Ihe spring oben exerts its pressure on the hub or collar 10, ancl, by turning i13, imparts the motion to the shaft 22 through the described gearing. This revo1ves the flexible shaft 27, operating the fzms, the movement of the fans being regulated by a suitable brake, such as the friction-screw 30. As soon as the power nf ehe spring is spent it is wound np again by applying the f00t to the treadle 31. 'lhis constrnction provides a cheap und simple n1eans for operating a fern.

YVe c1ain1 as our invention l. The combina-tion of a shaft carrying a fan, an inclosing tnbe, a base supporting the tube, a 1'0d traversing the base, a, spring surronnding said rod, a clncch conneeting the spring and r0d, a sleeve loose 011 snid r0d 0011- nected to the spring, and gearing loeat-ed between said s1eeve and shaft, substantially as an d f01' the pnrpose sei; forth.

2. The combination of a shaft, a fan seenred to the shaft, a tube inclosing the shaft, a base,a rod traversing the base, a spring surronnding the rod, a clutch having one men1- her secnred t0 the spring and the other memher secured t0 the 1'0d, a treadle secnred to sa-id rod f0r winding said spring, a spring for reurning said treadle t0 normal position, and gearing located between said spring and shaft, substantially zus an d for the purpose set forth.

3 The combination of a shaft, afan seeured Eo said shaft, the base, a 10d traversing said base, a spring surrounding the rod, a clutch having one n1ember 0 secured to said spring und the 0Lher men1ber 7 secnrecl to sa.id rod, a notched flange on said member 6, a paw1 engaging the notches of said fiange, atreadle secured to said rod, and gearing loose 011 the szrid rod and eonnected 130 said spring {und shaft, substantially zus set forth.

4. The combination of a shaft, n fan secured to the shaft, a tube inclosing ehe shaft, a base, a rod traversing the base, a spring snrrounding the r0d, the notched fiange 8, secured to the spring, a pruvl engaging said flange, n clntch forming a connection between 11110 spring and rod, a sleeve 100se 0n said rod C011- nected to the spring, and gearing located between said sleeve and shafb und consisting 0f genr-wheels 13, 16, und 18, pinions 14, 17, anc1 19, und bevel-wheels 20 and 21, substnntially as and for the pnrpose sei; forth.
